Comment (by ncohen):

 Dima: in Python a call to 'map' creates a new list in memory. Do you
 understand of painful that makes it to read changes like that?
 {{{
 -        for j in b:
 +        for j in map(lambda x: x[0], st.OrbitsDomain(b)):
 }}}
 A new list in memory only because you want j[0] instead of j?...

 Of course we don't care, or course it's totally negligible, but what the
 hell. Don'you want to write Python code instead of badly translating GAP
 code into Python?..
